Engineers will appreciate the integrated I/O configuration within the TM258LD42DT. This controller features 24 digital inputs and 16 transistor outputs on board. Consequently, users can deploy the unit without additional I/O modules for many applications.

Furthermore, the dual Ethernet ports enable sophisticated network topologies. These ports support Ethernet/IP, Modbus TCP, and machine bus protocols. This flexibility allows the TM258LD42DT to serve as a central hub for machine automation networks.

Integrated I/O and Interface Details

The digital inputs accept 24V DC signals from sensors and pushbuttons. The 16 transistor outputs deliver 0.5A per channel for solenoid and indicator control. Two analog input channels accept 0-10V signals for process monitoring.

The controller also includes two CANopen ports for drive and remote I/O connectivity. A USB port provides convenient programming access without network configuration. For reference, other Modicon M258 components share this same compact form factor.

Energy Storage and Data Integrity

The TM258LD42DT includes an integrated real-time clock with battery backup. This energy storage maintains time-stamped data and fault logs during power interruptions. Engineers can rely on this feature for diagnostic tracking and event analysis.

Programming Environment and Performance

You can program this logic controller using SoMachine or EcoStruxure Machine Expert software. The TM258LD42DT supports all five IEC 61131-3 programming languages. It executes instructions in just 0.03 microseconds per operation. This speed enables precise motion coordination and high-speed machine control.
